Stay cool and productive with the Cool Boss CB-28, a powerful medium-duty evaporative air cooler designed for industrial and commercial spaces. Perfect for use in warehouses, workshops, or outdoor job sites, the CB-28 utilizes advanced Honeycool™ evaporative media to deliver efficient, eco-friendly cooling at a fraction of the cost of traditional air conditioners. With a high air output of 9,020 CFM and a generous 2,125 sq. ft. coverage area, this cooler is built to handle intense heat without breaking your budget.
The CB-28 features an 80-gallon auto-refilling water reservoir, allowing hours of uninterrupted operation—even in locations without a continuous water supply. The combination of a 28” Blue Flex™ axial fan and variable fan speed/water flow controls ensures maximum airflow control for consistent, targeted cooling. Operating on standard 110V power, there’s no need for special wiring, making the CB-28 convenient and easy to use in almost any setting.
But the CB-28 isn’t just about airflow—it’s also packed with user-friendly extras. A built-in 80W LED floodlight brightens up your workspace with 4000 lumens of lighting, while integrated Bluetooth® stereo speakers let you wirelessly stream music or podcasts. Additional features like soft-touch LED controls, automatic water shutoff, and an antibacterial housing make this unit both functional and safe for daily use. Cool Boss delivers performance and comfort with a smart, efficient, and reliable solution for tough cooling demands.

Forklifts and Lift Gates
All of our Single Post, 2 Post, and 4 Post Lifts* require a forklift (or similar) to unload. Tire Changers and Balancers and other small items allow for a lift gate service (At no additional charge) Lift gate service will lower your order to street level. How do I know if a forklift is required? See the drop down options that show when you're attempting to place an order.

This is a common question and here's some alternatives:
Can I hand unload my order if I don't have a forklift?
